It's not inherently "bad" to make plans with people who aren't your friends in front of your current friends, but it can potentially lead to hurt feelings or misunderstandings if not handled with sensitivity. The key is to be considerate of your friends' feelings and ensure that they don't feel left out or excluded.
Here are some things to keep in mind:
Communication: If you're making plans with others in front of your friends, it's a good idea to explain the situation openly and honestly. Let your friends know that you're making plans with other people, but also emphasize that it doesn't change your friendship with them or the plans you might already have together.
Inclusivity: Whenever possible, consider including your friends in the plans or finding ways to involve them in the future. If you know the people you're making plans with, maybe you can arrange a gathering where everyone can meet and interact. This way, your friends won't feel like they're being left out of a separate social circle.
Balance: Strive to strike a balance between spending time with different groups of friends. Make sure you're not consistently prioritizing one group over the other, as this could lead to feelings of exclusion or neglect.
Be sensitive to their emotions: Understand that some people may feel more sensitive or left out in certain situations. If you notice any signs of discomfort or hurt feelings, take the time to address their concerns and reassure them of your friendship.
Respect their boundaries: If your friends express that they're not comfortable with certain plans or situations, respect their feelings and be willing to adjust your approach accordingly.
Ultimately, the key is to be aware of your friends' feelings and be considerate of their emotions. Open communication and empathy can go a long way in maintaining positive relationships with your friends while also socializing with others.
